digitalmars.D - My thoughts on D

Hello,

Maybe nobody cares, maybe not.

I use D for a month now.

It is great, the community is great.
Really easy to handle it enables to get the productivity it 
promises.

Almost.

I used to run c++. I don't even want to look at my codes now.

Instead, I run python along with D.

D is very powerful.

But it suffers in the details.

1) The library is getting wider. Good. But as of now, it is still 
TOO MUCH in the c++ style, in which you have to go to github to 
grab some non official libraries.
Sometimes it works, sometimes it won't (of course it will compile 
but not easy to use or error prone -> not a good standard for a 
language)

2) In comparison, when you use Python, everything is under your 
hand. No real need to go on github or so on to keep working. 
Everything feels "safe".
We miss a "gathering point". A bit like pip or the deprecated 
easy-install.

3) Some pages are not documented properly. And, as i am not 
someone pointing out the problems and hiding when time comes to 
propose solutions/solve them, I cannot even figure out the way 
some standard libraries are expected to work.
(e.g:json; the json.org might be helpful but, common, we should 
have it directly here, not traversing the web (exagerated) to 
find a clue).

4) Even the merge with 4.9 is no help on these points. Gathering 
people, yes, showing them a path to follow to be able to stick 
together, double yes.
But the latter seems, ATM, a big no.
I know many of you are really smart, so just take this 
mataphorism : Napoleon, even if one of the greatest commander, 
would have got far if no backed by generals and a great army 
knowing where it is going.
Let's make a courtesy to D : please do not let it be jailed in 
Elbe island. It only asks to fly.

It is definitely not a bad criticism, please do not take it for 
such platitude.
I would like to see D far beyond what it is currently.

You made a GREAT job. Now, let the community help. We need 
batteries included (python-like). Then everyone will like it: 
compiled-ultra speed + great useful and centralized libraries.

English is not my native speaking, please be kind with it :)

Thanks,

Larry

A point missed here : I was talking about helping to document. -> I cannot even figure out the way some standard libraries are expected to work in order to document them consistently

what library? phobos is standard library and distributed with compiler, so no need to checkout from githud often(in fact it could give u more troubles due to active dmd development), but if you talk about deimos than i must note this is just collection of C bindings(only), not standard library.

dub is a D package manager. Depending on your OS, you might have to download *it* from github, but after that you'll have a wide range of tools at your fingertips. http://code.dlang.org/

I was indeed refering to phobos, yes :)

I took the example of std.json.
Where are the examples to write, read a json file ?

http://dlang.org/phobos/std_json.html is absolutely helpless.

It is that : details.

When it will be fixed, D will really shine.

nothing, but it doesn't give me a clue how to actually use the package. But enough complaining, to improve the documentation would I 1) clone Phobos in github 2) improve the docs on my branch 3) request a (merge|pull|whatever the git verb is to apply my changes) Assuming that path is correct, to whom would I send the request to perform #3? If that path isn't correct how would I go about improving the docs for a part of Phobos? I'm willing to read code and put together examples as long as they are of some general utility. If I'm just doing it by myself for myself it's not worth my time.

You could have two schools of thought about this. Either have a library that includes as much as possible, everything that could be conceivably used. (Called "batteries included") Or a smaller library that focusus on the more common stuff that can be reasonably expected to used in most programs. (Called "some assembly required") The advantage of the former is that you don't have to hunt as much for lesser used code. The advantage of the latter is that it is easier to maintain and the library maintainers can focus on providing those components well, and have better assurances that what's in the library is of good quality. I don't know what Walter's long term plans are for Phobos, but I personally favour the latter. Also remember that D is still fairly young. It's code base is growing, and I image the library will grow too. Give it time.

I presume you mean a code repository where libraries are kept and can be downloaded and installed via a special program. One exists for D. Its called "dub".

You should just use a normal GitHub pull request vs https://github.com/D-Programming-Language/dlang.org master.

I agree that the documentation needs work. We're trying to work on that with the [dox] threads. :) Please speak up if you find other specific examples where the docs are not helpful. Or better yet, file bugs on it on the bugtracker (http://d.puremagic.com/issues) so that they don't get forgotten and lost in the forum archives.
